6mm 3 Core SWA Armoured Cable – Heavy-Duty Steel Wire Protection for Underground and Outdoor Power

Looking for a reliable, high-performance cable for underground or external installations? 6mm 3 Core Steel Wire Armoured (SWA) Cable is a robust solution, designed to carry mains electricity in residential, commercial, and industrial applications. It features a tough black PVC sheath, cross-linked polyethylene (XLPE) insulation, and stranded copper conductors with a galvanized steel wire armour for maximum mechanical protection.

📌 Key Applications

Direct burial in the ground (resistant to mechanical damage)
Outdoor electrical supply and lighting
Incoming mains for homes and commercial properties
Industrial power distribution networks

The XLPE insulation resists chemicals, oils, and UV exposure, making this cable suitable for harsh environments.
